Hello.
I would like to have the opportunity to zoom, like a fixed zoom all the time, like in iOS, where you can choose pinch to zoom, or fixed from 50-90%
Theis would make the screen more useable
Thank you!
the zooming feature in webview would not apply to things like the video player, it would just make the UI larger. If that is truly your goal open a feature request on github.
My goal is actually to make thing smaller
it still wouldnt change the size of the video player though, if you really want this feature please file a request in the github repo 
I created the feature request, in case anyone ending up here from a web search is interested: Implement lovelace-wide zoom option · Issue #4571 · home-assistant/android · GitHub
